1. A Novel Low-Power FPGA-based 1-1 MASH ΔΣ Time-to-Digital Converter Employing one Counter for both Stages

Ahmad Mouri Zadeh Khaki; Ebrahim Farshidi

Articles in Press, Accepted Manuscript, Available Online from 30 April 2020

Abstract
  In this paper, a novel continuous-time 1-1 MASH ∆∑ Time-to-digital converter (TDC) is presented. Since the proposed design utilizes 12-bit quantizer based on Gated Switched-Ring Oscillator (GSRO) for both stages, it has been implemented all-digitally. By using a novel structure, only one multi-bit ...  Read More

2. Fault Tolerance of RTMP Protocol for Live Video Streaming Applications in Hybrid Software-Defined Networks

Hamed Khanmirza; Arash Oloomi

Articles in Press, Accepted Manuscript, Available Online from 11 May 2020

Abstract
  Nowadays, video hosting services receive and stream videos using standard protocols like Real-Time Messaging Protocol (RTMP). During the streaming process, video file streams are usually divided into small multi-second parts, and the player receives these parts instead of the whole file at once. Most ...  Read More

3. On the Design of Coherent Zero-Forcing Receiver for the Flat Fading MIMO Multiple-Access Channels

Mohsen Sheikh-Hosseini

Articles in Press, Accepted Manuscript, Available Online from 11 May 2020

Abstract
  This paper investigates multiuser detection for space-time block coded (STBC) transmission over a flat-fading multiple-input multiple-output multiple-access channel consisting of J co-channel users each with N antennas and a zero-forcing coherent receiver equipping with M receiving antennas. For the ...  Read More

4. Using of Convolutional Sparse Representation and Discrete Wavelet Decomposition for Satellite Image Pansharpening

Alireza Sharifi

Articles in Press, Accepted Manuscript, Available Online from 11 May 2020

Abstract
  High resolution multi-spectral (HRMS) images are essential for most of the practical remote sensing applications. Pansharpening is an effective mechanism to produce HRMS image by integrating the significant structural details of panchromatic (PAN) image and rich spectral features of multi-spectral (MS) ...  Read More
